Either way, there will eventually be nine prizes available to unlock, although only seven of them have been revealed. These prizes are limited to varying (increasing) amounts of Likes, and will be unlocked in the final game upon launch if we reach those milestones in time. Here's the complete rundown:

Black Mohawk Hair - 20,000 Likes

Casino Row T-Shirt - 50,000 Likes

Graffiti Wall - 100,000 Likes

Skull Bandana - 250,000 Likes

Animated Lions - 500,000 Likes

Tribal Tattoo - 1 million Likes

Stripes Baseball Cap - 1.5 million Likes

Two additional prizes have yet to be revealed. So far, the game's Facebook fan page has only gained 70,000 Likes, so managing to unlock the Black Mohawk Hair and Casino Row T-Shirt as prizes. Since the game's announcement is so new, and the hype train has barely left the station, imagining you'll see that number climb slowly at first, and then monumentally as the game comes closer and closer to launch.
